Chapter 3, Problem 22EAP
Science or Nonscience?
Each of the following statements makes some type of claim. Decide in each case whether the claim could be evaluated scientifically or falls into the realm of nonscience. Explain clearly, not all of these have definitive answers, so your explanation is more important than your chosen answer.
22. A huge fleet of alien spacecraft will land on Earth and introduce an era of peace and prosperity on January 1, 2035.

- Which of the following is least reasonable regarding the difficulty in contacting extraterrestrial life using space flight and radio communication. Group of answer choices Space flight to the nearest star would take thousands of years with current technology. Even if another intelligent civilization is within a few hundred light-years of us, conversations would be very slow with a turnaround time of decades or even centuries. The spacecraft that NASA sent to Proxima Centauri a few years ago should be approaching its target within a decade or two, depending on solar wind conditions. Earth has been broadcasting at radio wavelengths since the 1930's, so any civilization within a radius of about 100 light-years or so could have received the broadcast by now. Without some major breakthrough, interstellar space flight is totally impractical.arrow_forwardSolve for ALL four questions using PROPER EXPLANATIONS, DETAILED DIAGRAMS AND EXPLAINING HOW THE ANSWER WAS JUSTIFIED.
